Unlocking iPhone through o2 (£15)

Nine_Lives

I have an iPhone 4S. I was going to go on Orange & got a test SIM for my old iPhone 3GS - everywhere was great, except for work, which is where i use my phone the most.

Since that though, Orange & T-Mobile seem to have merged into EE. A result of this has a lad i work with showing me how many bars signal he now gets at work - instead of 1, it's full.

I want to test this out on my new iPhone 4S, but need to pay the £15 to unlock it.


Question is, if anything goes wrong with my iPhone & i need to restore it etc, does this erase the unlock? Or once it's unlocked is that it - it's unlocked for good, regardless of anything that happens to it from thereon in?

A proper unlocking doesn't erase anything. For iPhones it's just a change in Apple's database. However, AFAIK, O2 unlock phones for free.

Unfortunately they don't (for me - PAYG) - http://service.o2.co.uk/IQ/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=Companion,question=ref%28User%29:str%28Mobile%29,CASE=17424

I'm not asking if it erases anything, i'm asking if once unlocked, let's say the iPhone ends up with a problem (for ease of understanding, let's say MONTHS after the unlock, totally unrelated to the unlock) which requires restoring.

Does the act of restoring 'undo' the unlock? Or is it a case of once unlocked, it's unlocked forever?

Proper unlocking (unlike jailbreaking) = forever.
